Halma plc (LSE: HLMA) is a group of technology companies that makes products for hazard detection and life protection.

It is listed on the London Stock Exchange and is a constituent of the FTSE 250 Index.

The Company was established in 1894 in Ceylon as The Nahalma Tea Estate Company Limited.

It switched to rubber production in 1937 and became The Nahalma Rubber Estate Company Limited.

During the early 1950s the Company's rubber estates were nationalised by the Sri-Lankan government, and in 1956 the Company became Halma Investments Limited, thereby severing its connections with both tea and rubber and becoming an investment and industrial holding company.

In the early 1970s the company began a sequence of acquisitions in the mechanical, electrical and electronic engineering sectors.

The Company was renamed Halma Limited in 1973.

Recent acquisitions have included Fibreguide, an optical fibres business, bought in 2008.
